I've been quite fascinated by the relative insignificance of human existence the shortness of life. We might as well be a letter in a word in a sentence on a page in a book in a library in a city in one country in this enormous universe! And that kind of fear and insignificance has kept me awake at night.
If you lock me in the room with a piano teacher for a year I might be able to knock out a rendition of 'Roll Out The Barrel ' but will I ever be a concert pianist? No.
